Some good news on the clean-energy front: Lithium mining in the Salton Sea in California will proceed, with Australian firm Controlled Thermal Resources beginning construction on a new mineral extraction and geothermal power plant.

The benefits of the Hell’s Kitchen project will be twofold: First, the lithium it will produce. The facility will initially output 25,000 metric tons of lithium hydroxide annually, with production projected to eventually reach 175,000 MT per year, if all goes well. Federal researchers say that the brine beneath the sea may contain enough lithium to make batteries for at least 375 million electric vehicles. Other estimates are higher. For perspective, there are fewer than 300 million autos of any kind on the road today.

Second, clean power — at least 50 megawatts is expected annually to start, possibly rising to 350 MW over time — generated from the superheated brine that contains the lithium. Unlike other clean power, geothermal can operate constantly, using the Earth’s heat. But there are only a few places, like the Salton Sea, where such projects are feasible.

Note that opponents of the project are still threatening lawsuits, with claims of insufficient environmental reviews and possibly harmful effects on nearby residents.
